| Background: Accurate voxel phantom is needed
for dosimetric simulation in radiation therapy for
malignant tumors in female pelvic region. However,
most of the existing voxel phantoms are constructed
on the basis of Caucasian or non-Chinese population.
Materials and Methods: A computational framework
for constructing female pelvic voxel phantom for
radiation dosimetry was performed based on Chinese
Visible Human (CVH) datasets. First, several organs
within pelvic region were segmented from CVH
datasets. Then, polygonization and voxelization were
performed based on the segmented organs and a 3D
computational phantom is built in the form of a set of
voxel arrays. Results: The generated phantom can be
converted and loaded into treatment planning system
for radiation dosimetry calculation. From the
observed dosimetric results of those organs and
structures, we can evaluate their absorbed dose and
implement some simulation studies. Conclusion: A
voxel female pelvic phantom was developed from
CVH datasets. It can be utilized for dosimetry evaluation
and planning simulation, which would be very
helpful to improve the clinical performance and
reduce the radiation toxicity on organ at risk (OAR).
